CVE-2007-6077

The session fixation protection mechanism in cgi_process.rb in Rails 1.2.4,
as used in Ruby on Rails, removes the :cookie_only attribute from the
DEFAULT_SESSION_OPTIONS constant, which effectively causes cookie_only to
be applied only to the first instantiation of CgiRequest, which allows
remote attackers to conduct session fixation attacks. NOTE: this is due to
an incomplete fix for CVE-2007-5380.
